Ready for all your friends to be jealous The Zone Offroad Products 6" Suspension Lift Kit for 1999-2006 Chevrolet 1500 Silverado & GMC 1500 Sierra pickups is the ultimate in style and performance. Whether you are just driving to work or playing on the trail, this system was designed to perform. The main crossmembers were designed to match the factory geometry with the new Zone CNC machined steering knuckles creating a true factory quality driving experience. Match this geometry with the heavy duty differential skid plate that locks the main crossemembers together and the compression struts that tie back to the frame and you have a system ready for some serious abuse!


CNC Machined ductile iron knuckles Differential skid plate included to protect the front differential and lock the crossmembers together Compression struts included to support the main crossmembers for serious off roading 1/4" thick steel used to make indestructible crossmembers 3-point differential mounting system correctly positions the differential so the factory driveshaft can be used
